Adjustable sirup measuring cup



Patented June 23, 1931 UNITED STATES FRANK E. rownnn, or ATHENS, GEORGiA ADJUSTABLE smur MEASURING our Application filed. June 8,

This invention relates to liquid measuring devices especially designed for filling bottles, an object being to provide means for use in connection with a bottle filling machine for adjusting the measuring device so that a predeterminedamount of liquid may'be dis-' pensed at each operation, and the device adjusted for bottles of different sizes.

Another object of the invention is the pro 1 vision of means of the above character which may be applied to a type of bottle filling machine now in use.

With the above and other objects in view,

the invention further includes the following commonly known as a syruper with the invention applied.

Figure 2 is an enlarged fragmentary sec tional view taken substantially on the line- 22 of Figure 1.

Figure 3 is a fragmentary elevation lllustrating the means for locking the measuring device in adjusted posit-ion. 3o

arm.

The invention is shown in connectioirwith a portion of a syruper usedfor supplying a predetermined quantity of sirup Ior botthng purposes, the machine including a sirup tank, a portion of which is shown at 10, and a filling tube 11 which extends from the tank and which is designed to direct the sirup or other liquid into a bottle. In the type of machine illustrated, use is made of ameasuring cup 12 which is mounted for slidlng movement on the filling tube 11, this cup being ordinarily submerged in the sirup and when the bottle is in position, this cup is automatically elevated until it reaches the top open end of the tube 11. As the cup moves upward it is filled to its capaclty wlth the sirup so that the entire contents of the cup pass downward through the tube. A portion of the mechanism for lifting Figure 1 is a sectional view showing a frag- Figure 4 is a detail plan View of the sliding 1928. Serial No. 283,870.

the cup is illustrated, and this includes a lifting rod 13 which is connected by means of an arm 14 with a rod 15, the latter being movable in a stationary tubular guide 16. Means controlled by engagement with the mouth of the bottle is employed for forcing the rod 15 upward, but as this means forms nopart of the present invention it is not believed necessary to illustrate it. The liftingrod 13 has its lower end connected with a collar 17 by means of a forked arm 18 and asthis collar 17 is connected with the cup 12, upward movement of the rod 13 willcarry the cup upward, while the connection between v the arm 18 and the sleeve 17 will permit the cup to be'rotated.

The foregoing is the construction employed in the syruper referred to, and in order to regulate the capacity of the cup'12 so as 'to bottles in accordance with the character of the 'sirupor'the size of the bottles, use is ordinarily made ofdisplacement weights or Washers. These are placed within the cup so that the latter will be of the desired ca pacity, but this method of regulationconsumes considerable time in changing washers and necessitates a relatively large number of these washers which frequently become misplaced or lost. v

The above and other disadvantageous features are overcome bythe present invention through the use of a false bottom 19 which is placed within the cup. This bottom is of disk'like formation and may have its upper face concaved, while extending downwardly from the bottom 19 is an exteriorly threaded sleeve 20. v

The sleeve 20 enters the collar 17 whose interior surface is likewise threaded, so that when the cup and the false bottom 19 are relatively rotated, the bottom will be moved vertically with respect to the cup. A hard rubber or other bushing 21 is located within the sleeve 20 and bears against the tube 11.

.The false bottom 19 has extending therethrough a rod 22 whoselower end threadedly engages the bottom 19 and whose upper end has non-rotatably secured thereto an arm 23. The arm 23 is bifurcated as at 24 so as to ex supply different amounts of sirup to the tend around the rod 13, so that the bottom 19 may be moved vertically and Will be held against rotary movement.

As thus far described, it will be seen that by rotating the cup 12, the bottom 19 will be moved vertically so as to increase or decrease the depth or capacity of the cup.

Mounted for sliding movement upon the rod 22 but held against rotation thereon due to the cross sectional shape of the rod is a dog 25, while mounted uponthe rod and bearing against the dog and against the arm 23 is a spring 26. This dog is adapted to engage any one of a number of spaced notches 27 provided in the edge of the cup, and the spring 26 will act to yieldingly hold the dog in engaged position.

It will be apparent from the foregoing description and accompanying drawings that the capacity of the cup may be quickly and conveniently regulated to regulate the quantity of liquid delivered at each operation of the machine and as the false bottom 19 has extending from its periphery a. split packing ring 28, leakage between the bottom and sides of the cup will be prevented without interfering with adjustment.

The invention is susceptible of various changes in its form, proportions and minor details of construction and the right is herein reserved to make such changes as properly fall within the scope of the appended claim.

Having described the invention what is claimed is:

The combination with a bottle filling machine, a measuring cup mounted for vertical and rotary movement and having spaced dog engaging means around its edge, a lifting rod for said cup to move the cup vertically, a false bottom Within the cup, means connected to the bottom and cup to provide for independent vertical aud rotary movement of said bottom to regulate the capacity of the cup, a vertically disposed rod carried by the false bottom, means carried by said rod for sliding engagement with the lifting rod, a spring influenced dog mounted upon the rod to engage the dog engaging means and yieldingly hold the false bottom and cup against accidental rotation.

In testimony whereof I afiiX my signature.
